For the sustainable development and conservation of the national land, planned development and efficient environmental conservation must be accompanied. To this end, it is possible to induce development and conservation to harmonize by deriving factors affecting development through analysis of previously developed areas and applying appropriate management measures to areas with high development pressure. In this study, the relationship between the area where the land cover changed from forest to urbanization and various social, geographical, and restrictive factors was implemented in a regression formula through logistic regression analysis, and potential development sites were analyzed for Yongin City. The factor that has the greatest impact on the analysis of potential development area is the restrict factors such as Green Belt and protected areas, and the factor with the least impact is the population density. About 148km²(52%) of Yongin-si's forests were analyzed as potential development area. Among the potential development sites, the area with excellent environmental value as a protected area and 1st grade on the Environment Conservation Value Assessment Map was derived as about 13km². Protected areas with high development potential were riparian buffer zone and special measurement area, and areas with excellent natural scenery and river were preferred as development areas. Protected areas allow certain actions to protect individual property rights. However, there is no clear permit criteria, and the environmental impact of permits is not understood. This is identified as a factor that prevents protected areas from functioning properly. Therefore, it needs to be managed through clear exception permit criteria and environmental impact monitoring.

This study considers the problem of reality that our floral art has to overcome as a loss of the floral art spirit caused by the expansion of Western-centered formalism flower culture, and considers the discussion on the deformality of distancing and the free spirit of nomadism. The floral art, which works on the creator's aesthetic mental world through flowers, is an art of mental image that values the free mental world of the creator. It also refers to the importance of artist consciousness as an art of self-imago that makes the target world beyond the "expression of similarity" that reproduces the target world. In this context, the lack of concern about the identity of Korean floral art appears to be the creative training and work of Korean floral artists who are biased toward Western expression techniques and creative methods. It also expresses a problem with our cultural consciousness, which is dominated by the Western flower culture of flower design. Here, we are obliged to understand the reality of Korean floral art biased by Western flower design and to organize discussions to solve the problem. Therefore, this study examines the problems that our floral art has to overcome as part of seeking the identity of Korean floral art and enhancing the cultural value of Korean floral art through criticism of Western cultural acceptance. This is a historical consideration of the nature of Korean floral art to recover, while also a process of identifying the meaning of the free creative spirit that the artist should maintain as an aesthetic art. Furthermore, such criticism of the Korean floral art culture and discussion of introspection are expected to serve as an opportunity to further expand the academic discourse system for the floral art while embodying the "identity" of Korean floral art.

Purpose: Conditions that limit activity constitute one of the important factors that threaten the health of the elderly. This study sought to analyze the dietary habits and nutritional intake status of the Korean elderly who were faced with activity limitations. Methods: Utilizing data from the 2019 Korea National Health and Nutrition Examination Survey, we classified 1,383 elderly people aged 65 and over into 2 groups: those with activity limitations (n = 222, LG) and those without (n = 1,161, NG). We conducted a comparative analysis of the general characteristics, dietary habits, intake of major food groups, energy, and major nutrients. The nutrient adequacy ratio (NAR), index of nutritional quality (INQ), and healthy eating practices were also analyzed. Complex sampling analysis was utilized for all the analyses with energy intake and socio-demographic variables adjusted. Results: The average age (73.8 years) of members of the LG was higher than those of the NG (72.6 years; p = 0.010). A higher percentage of participants in the LG lived alone (28.1%) compared to those in NG (17.2%; p = 0.004). The LG participants tended to regard their health status as "bad" or "very bad" (62.7%) more often than those in the NG (19.3%; p < 0.001). The LG subjects ate breakfast less frequently (p = 0.054) and ate out significantly less often than the NG subjects (p < 0.001). The LG subjects ate more grain (p = 0.001), fewer seeds (p = 0.014) and vegetables (p = 0.039). Carbohydrate made up a large percentage of their energy intake (p = 0.026). The LG subjects had significantly lower NARs of energy (p = 0.021), protein (p = 0.031), and riboflavin (p = 0.037). The LG participants also had a significantly lower rate of healthy eating practices (22.7%) compared to those in the NG (37.8%; p < 0.001). Conclusion: Activity-limited elderly, despite their need for appropriate dietary management, were poorly nourished. They were likely to live alone, thereby making it hard to provide them with social support. Hence, there is a need to provide nutrition education and policy support for the elderly bearing the burden of limited activity.

Purpose: This study examines the weight control behavior depending on university students' motives of using social media. Methods: The participants were 447 university students in the Jeonbuk area. Collected data were analyzed using factor analysis, cluster analysis, analysis of variance, and χ² tests with SPSS v. 26.0. Considering the motives of using social media, we investigated the usage of social media, dietary behavior related to social media, and weight control behavior. Results: Using the K-clustering method, the motives to use social media were categorized into three clusters: cluster 1 was the interest-centered group, cluster 2 was the multipurpose information-seeking group, and cluster 3 was the relationship-centered group. Among the various social media sites, YouTube (86.8%), Instagram (76.1%), and Facebook (61.1%) were the most visited by the subjects. The dietary behavior related to social media in cluster 2 was significantly higher than clusters 1 and 3 (p < 0.001). Clusters 1 and 2 showed a significantly higher dissatisfaction with one's weight (p < 0.05) and consequent interest in weight control than cluster 3 (p < 0.001). Cluster 2 used weight control-related information from social media significantly more than other clusters (p < 0.05). Weight control experiences in cluster 1 and 2 were significantly higher than in cluster 3 (p < 0.001). Conclusion: Differences in dietary behavior related to social media and weight control behavior were observed between cluster types of motivation to use social media. Based on the usage motives of university students and their behaviors, we propose that educational programs should be conducted for weight control using social media.

A stratum with a complex composition and a distributed low-permeability soil layer is difficult to remediate quickly because the soil remediation does not proceed easily. For efficient purification, the permeability should be improved and the soil remediation agent (H₂O₂) should be injected into the contaminated section to make sufficient contact with the TPH (Total petroleum hydrocarbons). This study analyzed a method for crack formation and effective delivery of the soil remediation agent based on pneumatic fracturing, plasma blasting, and vacuum suction (the PPV method) and compared its improvement effect relative to chemical oxidation. A demonstration test confirmed the effective delivery of the soil remediation agent to a site contaminated with TPH. The injection amount and injection time were monitored to calculate the delivery characteristics and the range of influence, and electrical resistivity surveying qualitatively confirmed changes in the underground environment. Permeability tests also evaluated and compared the permeability changes for each method. The amount of soil remediation agent injected was increased by about 4.74 to 7.48 times in the experimental group (PPV method) compared with the control group (chemical oxidation); the PPV method allowed injection rates per unit time (L/min) about 5.00 to 7.54 times quicker than the control method. Electrical resistivity measurements assessed that in the PPV method, the diffusion of H₂O₂2 and other fluids to the surface soil layer reduced the low resistivity change ratio: the horizontal change ratio between the injection well and the extraction well decreased the resistivity by about 1.12 to 2.38 times. Quantitative evaluation of hydraulic conductivity at the end of the test found that the control group had 21.1% of the original hydraulic conductivity and the experimental group retained 81.3% of the initial value, close to the initial permeability coefficient. Calculated radii of influence based on the survey results showed that the results of the PPV method were improved by 220% on average compared with those of the control group.

The objective of the study was to examine the associations of dietary carbohydrate and fat intake with the prevalence of metabolic syndrome in Korean women. A cross-sectional study was employed based on data from the Korea National Health and Nutrition Examination (2007-2016). A total of 22,850 women aged 19 to 69 years were studied after excluding responses from pregnant or lactating women and those with missing metabolic values. Dietary intake data were collected with a 24-hour recall method. Dietary carbohydrate and fat intakes were divided into quintiles. After controlling for confounding variables, a multivariable logistic regression and general linear model were used. The findings indicated that HDL cholesterol levels were lower (p for trend<0.01), while triglyceride levels (p for trend=0.04), waist circumference (p for trend<0.01), and systolic blood pressure (p for trend<0.01) were higher among participants in the highest quintile of carbohydrate intake compared to those in the lowest quintile. Participants in the highest quintile of fat intake had lower waist circumference (p for trend=0.02), triglyceride level (p for trend<0.01), and systolic blood pressure (p for trend<0.01), while higher HDL cholesterol level (p for trend<0.01) compared to those in the lowest fat intake quintile. Metabolic syndrome was more likely to be present in the highest quintile of carbohydrates intake than in the lowest quintile (5^th quintile vs. 1^st quintile, OR: 1.32; 95% CI: 1.11 to 1.57). However, metabolic syndrome was less likely to be present in the highest quintile of fat intake than in the lowest quintile (5^th quintile vs. 1^st quintile, OR: 0.73; 95% CI: 0.61 to 0.86). This study revealed that high dietary carbohydrate intake and low dietary fat intake were associated with metabolic syndrome in Korean women.

Farmers' band music is a religious ritual in Korea. It is a solemn ritual to exhibit the auspicious holiness of the people to the God. Most of the ritual is accomplished by music. The music of the farmers 'band, in this sense, has its meaning as the expression of holiness by sound. In this paper, I will explore the principle to make various rhythms of farmers' band music, especially focusing on the chaegut (lit. "stroke music"). It is very symbolic because the name of the music shows the strokes of the gong, called jing, in a rhythmic phrase. In this sense, the chaegut is man-made music based on the specific principles in accordance with the strokes of the gong. Among many chaegut rhythms, samchae (lit. "three strokes") to chilchae (lit. "seven strokes") are the main rhythms. They were made after the principle of 'forward with drums, backward with gongs' in Five way procession. It the basic principle of military procession from the early Joseon Dynasty. The procession follows with the sound of the drums and gongs. There was always a principle of "five strokes" to control the procession. The "five strokes" became the basis of the making of chaegut rhythms. The rhythms of the samchae to chilchae are based on the rhythm of samchae. The samchae has three gong strokes in a cycle, which exhibits the chaotic moment with the rhythmic noise. The name of the rhythm exhibits the correspondence of the signifiant, that is the name "three strokes" and the signifié, that is the real three strokes of gongs in music. Other four rhythms has made up from the samchae with half cycles are added in accordance with the strokes of the gongs. In this way, the chaegut shows the principle of "five strokes" in the military procession. The rhythm of ochae jilgut is a mixture of ochae (lit. "five strokes") and jilgut (lit. "road music") which is usually performed on the road to a mountain shrine. The musical structure of ochae jilgut corresponds to the colotomic structure of Southeast Asian music and the 15th-century music of old musical scores. The rhythm of gilgunak chilchae is a mixture of gilgunak (lit. "road military music") and chilchae (lit. "seven strokes"). The rhythmic structure is similar to other regional music, sijo ("short song") of the literati music and norae garak (lit. "some melody") of the shaman music. In sum, the chaegut is very artistic music made from the military procession of the Joseon Dynasty. The name of the rhythm corresponds with the strokes of the gong in a cycle. In this way, the chaegut shows the principle of music-making to exhibit the ritual characteristics of the Korean people.

This paper aimed to clarify the identity and category of the Jeong Jeongnyeol-je Chunhyangga from the perspective of the pansori transfer, while revealing the trajectory of Jeong Jeong-ryeol-je Chunhyangga, which remains in the modern pansori. Jeong Jeong-ryeol's Chunhyangga pansori part has been handed out to date, and except for the love song section, the pansori section, which corresponds to the love-separate-suffering-reunion paragraph, is almost complete. In the case of "Lee Doryeong enters Dongheon," "Hwangneungmyo song," and "The royal secret inspector visits Chunhyang's house to console her", there is a difference in pansori rhythm compared to Chunhyangga, which is currently held. "Why Yi Doryeong came to Chunhyang's House" is used in the form of an Aniri in the current Chunhyangga and "Chunhyang is treated as a virtuous woman in Namwon" is the only one included in Park Rokju's Changbon. "The royal secret inspector gathers people of Namwon to give a feast" is a new part that is not found in Chunhyangga, which is now being held, and can be seen as the Changgeuk sori of pursuing theatrical fun. On the other hand, this paper confirmed that the period between 1936 and 1937, when the Joseon Traditional Vocal Music Group actively performed Changgeuk and the record companies released a series of Changgeuk records, such as and , was an important time for the re-establishment of the Jeong Jeong-ryeol-je Chunhyangga, and that the Chunhyangga of those who had learned it before 1936-1937 was different from those who had learned it after that period. The preceding group includes Park Rok-ju, Kim Yeo-ran and Kim So-hee, while the latter group includes Kim Yeon-soo, Jung Kwang-soo, Park Dong-jin, Jung Kwang-soo and Kang Do-geun. In addition, except for Kim So-hee, these two groups are divided by the time they have learned Jeong Jeong-ryeol-je, whether they inherit the Jeong Jeong-ryeol-je from beginning to end, and by the gender of male and female singers. In teaching his pupils, Jeong Jeong-ryeol chose to use the "old-fashioned pansori" teaching method with impromptu plate-making in mind and the "modern pansori" teaching method with stereotyped sounds in mind. As a result, there were two aspects of Jeong Jeongryeol-je Chunhyangga's succession: a female singer-centered succession, which was held as learned from beginning to end, and a male singer-centered succession, which was held differently depending on the pansori schools or versions.

Carbon management is emerging as an important factor for global warming control, and land use change is considered one of the causes. To quantify the changes in carbon stocks due to development, this study attempted to calculate carbon storage by borrowing the formula of the InVEST Carbon Storage and Sequestration Model (InVEST Model). Before analyzing carbon stocks, a carbon pool was compiled based on previous studies in Korea. Then, we estimated the change in carbon stocks according to the development of Osong National Industrial Park (ONIP) and the application of alternatives. The analysis shows that 16,789.5 MgC will be emitted under Alternative 1 and 16,305.3 MgC under Alternative 2. These emissions account for 44.4% and 43.1% of the pre-project carbon stock, respectively, and shows that choosing Alternative 2 is advantageous for reducing carbon emissions. The difference is likely due to the difference in grassland area between Alternatives 1 and 2. Even if Alternative 2 is selected, efforts are needed to increase the carbon storage effect by managing the appropriate level of green cover in the grassland, creating multi-layered vegetation, and installing low-energy facilities. In addition, it is suggested to conserve wetlands that can be lost during the stream improvement process or to create artificial wetlands to increase carbon storage. The assessment of carbon storage using carbon pools by land cover can improve the objectivity of comparison and evaluation analysis results for land use plans in Environmental Impact Assessment and Strategic Environmental Impact Assessment. In addition, the carbon pool generated in this study is expected to be used as a basis for improving the accuracy of such analyses.
